Struct

A struct in Go is a data structure that is composed of fields, where each field has a type. Here is what a Go struct looks like:

type myStruct struct{    intField int    stringField string    sliceField []int}

The preceding code creates a struct type that is called myStruct, which contains three fields:

• intField of type int
• stringField of type string
• sliceField of type []int

You can then initialize and use that struct type in your code:

var s = myStruct{intField: 3,stringField: "three",sliceField : []int{1,2,3},}

The preceding method of initialization is also known as struct literals. There is a shorter version of it that looks like this:

var s = myStruct{3,"three",[]int{1,2,3}}

You can also use what is known as dot notation, which looks ...
